Title: Electric switching apparatus particularly for automatic line sectionalizers
IPC: H01H75/04
Filed: 1962-07-18
Abstract: 958,332. Automatic circuit-breakers. WEST INGHOUSE ELECTRIC CORPORATION July 18, 1962 [Sept. 19, 1961], No. 27597/62 Heading H2B. In a circuit-breaker, such as a gas-filled automatic line sectionalizer or an automatic reclosing circuit-breaker, having means tc cause tripping or final tripping on the occur rence of a number of overload conditions, ar electrically responsive means may change the position of a stop to alter the initial position of a counting device to change the number of occurrences necessary to produce the tripping or final tripping. In the arrangement shown overload current through a coil 28 raises ar armature 29 to turn a lever 36 so that a paw 39 is moved below a tooth 22 of a wheel 11 When the overload ceases, a spring 30 restores the lever 36 so that the wheel 11 is advanced one step. The wheel 11 is connected by gearing and a unidirectional clutch formed by a ratchel 50 and pawl 51 to an escapement 57, 59 which delays the resetting of the wheel 11 under the bias of a spring 24. Should further overload conditions occur in quick succession, the whee 11 is stepped round by the lever 36 until a projection 23 on the wheel 11 engages and moves a trip bar 13 to release a moving contact 14 The initial position of the wheel 11 is deter mined by a stop member 68 extending from E permanent magnet 72 which co-operates with keepers or electromagnets 70, 71. By provid ing an impulse of direct current of appropriate polarity to coils 73, the magnet 72 is moved from one to the other of the keepers 70, 71 to raise or lower the stop member 68, the magnet being retained by the keeper 70 or 71 when the impulse ceases.

Title: Process for separating into their constituent azeotropic mixtures of methanol and low-boiling aliphatic esters
IPC: C08F2/38
Filed: 1967-06-15
Abstract: 1,166,928. Organic mixtures; azeotropic distillation. MELLE-BEZONS. 15 June, 1967 [22 June, 1966; 1 March, 1967], No. 27754,67. Heading B1B. [Also in Division C2] Methanol is separated from a mixture comprising methanol, a low-boiling ester, e.g. methyl acrylate, which forms an azeotrope with methanol, an organic substance having a boiling point above the ester, and water by feeding the mixture through pipe 4 into distillation column I which contains a saturated C 1- C 7  hydrocarbon, e.g. cyclohexane in the vapour state. Vapours comprising methanol and hydrocarbon leave the head of column 1 and pass to condenser 10. The condensate flows to cool decanter 8 where two liquid layers are formed. The hydrocarbon layer and part of the methanol layer are returned through pipe 7 to column 1; and the remainder of the methanol layer is passed to distillation column 23 where it is freed from residual hydrocarbon and, possibly, ester. Pure methanol is withdrawn through pipe 26. The liquid which reaches the base of column 1 is passed to a hot decanter 3, where the liquid separates into an aqueous layer and an organic layer. The organic layer is fractionated in column 2, and the overhead vapours (methanol + water) is returned to column i through pipe 13. The mixture of ester and higher-boiling organic substance, withdrawn from the base of column 2, is separated in column 17. The aqueous layer from decanter 3 is fractionated in column 18. Vapours of ester and water flows from the head of column 18 into column 1; and water is discharged from the base of column 18. A polymerization inhibitor, such as hydroquinone, may be introduced into the system through pipes 27, 28. An aqueous solution of a copper salt may be introduced into the lower part of column 1 and the upper part of column 2.

Splitting-machines.-A machine for bevelling the ends of leather belts, comprises means for automatically cutting the taper by gradually moving a supporting roller towards a splitting knife under control of a screwed conical cam. A belt is pulled through the machine, by feed rollers a, b geared to a, handle f against a knife g which can be fixed to the frame of the machine or oscillated by a cam groove s engaging a knife extension h. A supporting roller i is carried in a frame swung about a shaft t under control of a conical cam m held from rotating by a pawl o, and mounted on a screw n. In operation, the belt is placed under the knife g and the roller i adjusted by a nut p until a pointer indicates the thickness of the belt on a scale v. The end of the belt is then placed against the indicated thickness marked on a table u which denotes the proper sized cone to be threaded on the screw n. A modification is described in which the knife is stationary but has a positioning movement and the belt is fed through the machine by a reciprocating gripper.

Title: Improvements in or relating to fuel for gas turbine engines
IPC: C10L1/12
Filed: 1951-05-03
Abstract: A fuel for gas turbine engines comprises a mixture of a petroleum residue fraction and a minor proportion of magnesium oxide or carbonate.  The magnesium compound may be employed in an amount sufficient to provide up to 3 per cent. of magnesium, based on the weight of the fuel.  If desired, a mixture of magnesium oxide and carbonate may be used.  The presence of the magnesium compound materially reduces or prevents the formation of deposits upon interior surfaces of the engine, such as upon the stator and rotor blades.  Corrosion by vanadium pentoxide present in the deposits is also greatly reduced or entirely eliminated.  The petroleum residue fraction may be furnace oil or Admirralty fuel oil.  According to the Provisional Specification, any oil-insoluble compound of magnesium or zinc may be employed instead of magnesium oxide or carbonate, and zinc oxide and zinc carbonate are mentioned.  Specification 689,579 is referred to.

Title: Improvements in the production of carbon black
IPC: C09C1/48
Filed: 1933-10-14
Abstract: <PICT:0427396/III/1> <PICT:0427396/III/2> In the production of carbon black by decomposition of carbon monoxide at about 400 DEG  C., in presence of a catalyst such as iron oxide (Fe2O3), the gas is passed upwards through a reaction vessel at a speed less than that which is sufficient to carry away the carbon at the same rate as it is formed, the accumulated carbon is kept agitated, and is subsequently removed by increasing the speed of the gas above this rate.  The gas which may be preheated to 500 DEG  C., enters by a pipe 4 at the base of the reaction vessel 1 and leaves by a pipe 6 containing a regulating valve 6<1> to a separator 14.  Catalyst is supplied through an inlet 5.  The reaction chamber may be fitted with a jacket for circulation of superheated steam at 700 DEG  C., or combustion gases to start the reaction or of cool air or gas to carry away the heat of reaction. The gas may be passed down through a central tube surrounding a rotary shaft carrying a nozzle which serves as an injector and agitating vanes at the base of the chamber. Agitation may also be effected by varying the pressure of the gas. Passage of pure carbon monoxide may be alternated with passage of producer gas or other industrial gas containing a high proportion of carbon monoxide.  The reaction with pure carbon monoxide may be effected in a narrow reaction chamber 2<1>, Fig. 5, supplied with gas and catalyst by a pipe 4<1>, the carbon and catalyst being carried by the gas into a wider chamber 2<2> supplied with industrial gas by a concentric pipe 4<2>.
